It was a definite inside job. I can't believe the SS didn't secure the rooftop of that building. They identified it as a problem but didn't secure it because it was outside the perimeter. Instead they relied on local law enforcement that supposedly confronted the shooter on the roof but backed away when he pointed the gun at him. I haven't heard much about the local law enforcement response, but I think the building should have been secured by the SS.

Trump didn't have his usual SS team of agents because on that day both Kamala and Jill Biden had rallies in PA. More agents were sent to Jill's rally and Trump received some temporary agents. That seems like an odd choice. How many people could have been at her rally compared to a Trump rally?

It looks more and more like a government-coordinated assassination operation to me.
